On Sunday morning, the Broncos had John Fox as their head coach, Adam Gase and Jack Del Rio as their top two assistant coaches and expectations of winning the Super Bowl.

On Wednesday, Del Rio was named head coach of the rival Oakland Raiders, Fox was interviewing for the Chicago Bears’ head coaching job — which he is expected to get — and Gase learned he finished second in the two-man race to become the San Francisco 49ers’ head coach. And, the Broncos are planning for the offseason.

Otherwise, not much happened over the past 72 hours.

Del Rio is the Raiders’ head coach after they agreed to terms Wednesday on a four-year contract, according to an NFL source.

The Broncos’ defensive coordinator the past three seasons, Del Rio, 51, seemed to be the top choice of Raiders owner Mark Davis since at least the final weeks of the season.

Before the Raiders-Broncos game to end the regular season Dec. 28 at Sports Authority Field at Mile High, Davis didn’t hide his affections as he walked over to chat up Del Rio, who grew up in the East Bay Area city of Hayward, Calif.

This will be Del Rio’s second NFL head coaching job — and third if you include his 3-1 interim stint with the Broncos in 2013. He led the Jacksonville Jaguars to a nine-year record of 68-71 from 2003-11 that included two playoff appearances.

The Broncos’ defense ranked No. 2 in 2012 and No. 3 in 2014 with Del Rio as their defensive coordinator. Beset by injuries and medical setbacks in 2013 to starters Kevin Vickerson, Rahim Moore, Derek Wolfe and Von Miller, Del Rio put together his unit into a solid late-season run that helped the team wind up in the Super Bowl.

Thus, the Fox coaching tree continues to branch out in the AFC West. Two years ago, Broncos offensive coordinator Mike McCoy became head coach of the San Diego Chargers.

Only now the tree has been uprooted. Fox and the Broncos mutually agreed to part ways Monday. Fox interviewed Wednesday in Chicago and flew back to Denver.

Gase, the Broncos’ offensive coordinator, had a mixed day Wednesday. After interviewing for a second time with the 49ers on Tuesday, Gase and San Francisco defensive line coach Jim Tomsula became the two finalists. Tomsula was the choice to succeed Jim Harbaugh as the 49ers’ new coach. However, Gase, the Broncos’ offensive coordinator, spent Wednesday morning talking with general manager John Elway about Denver’s head coaching position.

Gase declined comment Wednesday but acknowledged he received phone calls from San Francisco owner Jed York and general manager Trent Baalke notifying him of their decision.

Mike Klis was with The Denver Post from Jan. 1, 1998 before leaving in 2015 to join KUSA 9News. He covered the Rockies and Major League Baseball until the 2005 All-Star break, when he was asked to start covering the Broncos.
